Traffic cones often signal some sort of disaster or messy construction zone, but NYC architecture firm EFGH has managed to upcycle the orange cones into something beautiful with this 15×15′ Hedgehog concert pavilion. The whole thing can be constructed in just six hours, and by using already-manufactured traffic cones the architecture firm saved considerable costs on materials.

EFGH was given a short amount of time to make a stage for a Virgin Mobile event intended to raise awareness about youth homelessness. The result: a festive pop-up pavilion made from a steel frame studded with traffic cones. Check out the video below to see the pavilion being constructed.
